CONFIG_LOADADDR vs CONFIG_SYS_LOAD_ADDR

Hi.

I sometimes get confused by similar naming macros.

In my understanding, CONFIG_LOADADDR or CONFIG_SYS_LOAD_ADDR is used as default address by such commands as "bootm", "tftpboot", etc.

If both are defined, it looks like CONFIG_LOADADDR takes precedence (as far as I tested).

Do we need both?
Is it a good idea to merge them?
